Well wish this was a better post... took the car out for the first time on the highway. I have driven the car 4-5 times and about 25miles since I got it but only around town. Finally had some time today on the morning to go for a ride on the highway and actually experience the car....let the car warm up a bit and drove to highway, maybe a 7-8 min ride to highway etc...

Well drove the car normally and then finally gave it some gas, boost to maybe 6500+rpm and poof, a light pop and what sounded like maybe a blow off valve psssss and the car died.... I was rolling down hill on a bridge... engaged clutch and released and the car re-started but bogged out..like choked out... tried a another time and same, car choked right out but did start for a moment. NO white smoke out of rear etc... well wont get into the tow experience (3hrs, no tow hook in car, believe transport company took when delivered by error, flagged down a boxster owner and he let me borrow)

We got the car to safe place... (hard on a sunday) and to a porsche techs house... we gave it a try to start and the car did turn over but was running VERY rough and rich...black smoke (not thick smoke but black still) from tailpipes and smell of gas clearly running rich... we shut it right down....

Will try and diagnose early next week...I never added oil, or over filled, checked oil level last week and seemed OK, car passed PPI well, etc etc...

Praying its nothing major....
any thoughts? Also small box in rear underside by exhaust leaking some oil? car does have a check valve kit installed I believe, not sure if this is something that will help from major failure? At a loss I will admit as I don't know much about these cars...

Thanks all...

Turbo to intercooler hose pop off? Good luck

mickfluff

You may have nailed it buddy.... the tech called and said a hose to one of the turbo's may have blown off etc.... he looked at the other and said it looked a little worn etc so we are ordering both and replacing... I am hoping this is it as he said this is nothing major if this turns out to be the issue.... fingers crossed and will know more next week.,..

One of my hoses blew off my 996TT and all of a sudden my instrument panel lit up like a christmas tree. I was very concerned until the tech said "you didn't put the hose on correctly when you changed your plugs" .
Let's hope for a good ending to this saga.

sounds like a turbo > intercooler pipe let go - happened to me once and was scary till I popped the lid and saw the RH hose had let go.
(mine also happened on high boost 1.1 barg.)

good luck

Hope you resolve the problem soon, good luck

If your tech replaces the boost hoses, make sure he changes the factory hose clamps to Breeze clamps or equivalent.

Indeed on the Breeze clamps. Also use the uprated 1997 Turbo hoses with the orange ends.

Intercooler hose poping off is something owners should know how to diagnose and repair (at least temporarily) to avoid being stranded, particularly for longish trips. The other couple of things are a Dme relay and a twelve pt tool/extra fan belt... The oil infortunately that you show in your pics are probably from a leaky turbo

if my guy has issue locating parts shipped to RI in time any recomendation where i can get parts shipped in next day? Or 993tt hoses readily available at most dealers? he goes on vacation Thurs. for 3 weeks so hoping its on and it in time...to get to the planned next stp next week for the other works I had planned...

thanks again all...

It happened to me during a spirited drive down some twisty roads. I was accelerating hard and heard the same sound. I knew right away that the intercooler hose came off. I now drive around with a couple of wrenches and sockets in my car for this specific problem. Now if this problem happens again, I will be more ready to fix the car on the spot.

Very common for the 964T also to blow the hose of the intercooler.. Same thread pops up a few times a year. Hoping it is this easy fix for you

That kind of a sudden rich condition is almost always a boost hose. Even 997tt are prone to it.
I always carried a roll of duct tape just in case.
My 930 has built in tow hooks in the front, I believe my 993tt had the same, but I could be wrong.
